日常开发中图表还是很常见的,简单图标我们一般都用echarts 图表库,为什么选择 echarts简单上手容易,可以满足我们所有的开发需要,echarts也是国内做的最好的可视化库之一,API文档也比较详细.
npm install echarts --save
//或者
npm install echarts -S
也可以使用国内的淘宝镜像安装
npm install -g cnpm --registry=https://registry.npm.taobao.org
cnpm install echarts -S
在安装完成之后,在 main.js 中全局引入 echarts
import echarts from "echarts";
Vue.prototype.$echarts = echarts;
<template>
<div id="app">
<div id="main" style="width: 600px;height:400px;"></div>
</div>
</template>
export default {
name: "app",
methods: {
drawChart() {
// 基于准备好的dom,初始化echarts实例
let myChart = this.$echarts.init(document.getElementById("main"));
// 指定图表的配置项和数据
let option = {
title: {
text: "ECharts 入门示例"
},
tooltip: {},
legend: {
data: ["销量"]
},
xAxis: {
data: ["衬衫", "羊毛衫", "雪纺衫", "裤子", "高跟鞋", "袜子"]
},
yAxis: {},
series: [
{
name: "销量",
type: "bar",
data: [5, 20, 36, 10, 10, 20]
}
]
};
// 使用刚指定的配置项和数据显示图表。
myChart.setOption(option);
}
},
mounted() {
this.drawChart();
}
};

<div id="app">
<v-chart class="my-chart" :options="bar"/>
